Electrical Resistivity Tomography for the 2D and 3D Investigation of Pingos and Permafrost Mounds in Northern Canada's Mountain and Coastland Areas

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 804-829, October/December 2026.
ABSTRACT Pingos and related permafrost mounds are widespread periglacial landforms in Arctic environments that are ice‐rich on the one hand and contain taliks on the other, making them vulnerable to climate change. So far, the interior, geophysical characteristics, and distribution of ground ice within these dome‐ or cone‐shaped features have not been ...

Seasonal patterns in greenhouse gas emissions from different types of thermokarst lakes in Central Yakutia (Eastern Siberia) [PDF]

, 2021
International audienceIn the ice‐rich permafrost area of Central Yakutia (Eastern Siberia, Russia), climate warming and other natural and anthropogenic disturbances have caused permafrost degradation and soil subsidence, resulting in the formation of ...

Frequency‐Domain Airborne Electromagnetic Imaging of Permafrost Reveals Heterogeneity and Drivers of Permafrost Change in the Discontinuous Permafrost Zone of Northwestern Canada

AGU Advances, Volume 7, Issue 7, October 2026.
Abstract Northern permafrost landscapes are undergoing rapid warming and thaw, yet the three‐dimensional subsurface structure that governs thaw vulnerability and landscape response remains poorly resolved by conventional ground temperature monitoring and satellite remote sensing.

Rapid Increase in Geogenic CO2 Emissions from Antarctic Permafrost

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Thawing permafrost can amplify climate change by releasing previously stored carbon, but observations of this feedback come mainly from the Arctic. Ice‐free Antarctic terrains are generally regarded as minor CO2 sources, although sub‐permafrost brines and deep carbon reservoirs may support localized geogenic degassing.

Methane Uptake by Inland Waters: Fact or Fiction?

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Inland waters are widely known as net emitters of methane (CH4) to the atmosphere, contributing ∼15% of global CH4 emissions. CH4 is produced by anaerobic methanogens in aquatic sediments, but net CH4 emissions at the water–air interface are modulated by CH4 oxidation by methanotrophs in the water column.

Constraining bubbling of methane from thermokarst lakes [PDF]

Eos, Transactions American Geophysical Union, 2013
In northern thermokarst lakes, which form in depressions left as permafrost thaws, methane, a greenhouse gas, can be released from lake sediments to the atmosphere through bubbling, or ebullition. Constraining the amount of methane released through bubbling would help scientists understand the role of thawing permafrost in the carbon cycle and global ...

Characterizing Permafrost Distribution Along the Hudson Bay Railway Using Temperature‐Calibrated Electrical Resistivity Tomography

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract As the climate warms, understanding permafrost distribution along linear infrastructure is a key aspect of assessing, mitigating, and adapting to the risks associated with permafrost thaw. Electrical resistivity tomography (ERT) is becoming an increasingly common tool for evaluating permafrost distribution at the infrastructure scale.

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

Boreas, Volume 55, Issue 4, Page 1073-1101, October 2026.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...
